1. Statements in C Programming
LOOPING
Statements in C Programming

2. For example you want to print the same words ten times.
Introduction
C programming language, there are circumstances where you want to do the same thing many times
For example you want to print the same words ten times.
You could type ten printf function, but it is easier to use a loop. The only thing you have to do is to setup a loop that execute the same printf function ten times

3. Looping statements are also called as iterative statements
What is a LOOP?
A loop is defined as a block of statements, which are repeatedly executed for a certain number of times
Looping statements are used for running a set of statements for any number of times
Looping statements are also called as iterative statements

4. Types of LOOPs? Unbounded loop Bounded loop
In C Programming there are mainly two types of loops
Unbounded loop
Bounded loop
Note
These are also called indefinite and definite loops respectively

5. Types of LOOPs? Unbounded loop Bounded loop
while statement
Unbounded loop
do - while statement
Bounded loop
for statement

6. Unbounded loop
Unbounded looping statements are used when we don’t know how many times the set of statements has to be repeat
Unbounded looping statements can either be a Pre – Test Loop or be a Post – Test Loop
In Pre – Test Loop, condition is checked before the beginning of each iteration. If condition is TRUE repetition is performed, if it is FALSE repetition is not performed

7. Pre – Test loop is implemented using ‘while’ statement
In Post – Test Loop, first the block of statements to be repeat is executed then condition will be tested
That means in Post – Test Loop, condition is checked after executing the repeating statements, if the condition is TRUE it repeat the statements again, if it is FALSE repetition is not performed
Post – Test loop is implemented using ‘do - while’ statement

8. While statement counter initialization; while(condition) {
block of statements;
…..
counter modification; }
Syntax

9. Example F T #include<stdio.h> void main() { int i=1;
while(i <= 10)
printf(“MRIT\n”);
i++; }
printf(“END”);
int i = 1 F
i<=10 T
printf….MRIT
i++
printf….END
